Test case attached.

In Python 3.6, ssl tries to validate the hostname on its own, but fails to convert the SSL certificates hostname from IDNA back to UTF-8 and mismatches. Python 3.7 and master are unaffected since this got fixed by accident when validation was changed to depend on OpenSSL alone and not do it in python though the underlying match_hostname function is still bugged.
